HEItll/ltlil J. BRENNECKE, 0F CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO FRANK IHRGKE, OF CHICAGO, ILLINOIS,

Application filed February 2, 1914.

To all wlwm- 'it may concern:

lie it known thatI l',llnni\mu J. BREN- iufztg'nn, a eitizen of the United States, resid- 'ing at Chicago, in the county of (look and State et' illinois, have invented eertain new and useful VIxnproveinents in Goggles, of whieh the. Following is a sl'ieeifieation.

My inxention relates to eye-glasses of the type known as goggles and has particular referente to their general use by drivers ot autinnobiles.

The objects ot this invention are to over come the several objections to the relative niovability et the lenses attained by hinging these lenses tt'igrether, among which ohjeetions may be mentioned the lael( ot' .flexibib ity in the hinge, a flexibility that is necessary to permit the lenses to adjust themselves snugly against the temples, breaking ot lens es where the hinges are attached, laek oi support between the lenses that will eopen ate with the hows to hold the goggles saute against the il'aee and prevent them 'from bulgingw out over the nose of the wearer, and lark oi meai'ts toeholding the lenses nor- .really alined.

ill/ith these objeets in view the invention Censis s in the novel eonstruetit'n'i el goggles, combina tion and arrangement of parts therein, all asl'iereimtfter described in detail, illustrated. in the aoco:npanying drawing'A and more particularly pointed out in the append ed Claims.

ln the drawing-Figure ll, is a laee view oi. ay pair of goggles endlodying` my invern tion. il an edge view thereof. Fig. 3 is an edge view with the flexible eonneetion between the lenses twisted so that the lenses are oppositely inclined, and naeh at au angle relative to what would, be the axis of the hinge in a similar device 'using a hinge. Fig. il an enlarged seetional view of the hinge joint itsel t with seetions of the` lenses broken aivay.l liig. 5 illustraties the flexibility of. the eonneetion whieh l; have substituted for the hinge, iu another direetion than that shown in Fig. 2l. lfigg. t3 is a moditieatitm olf lifig. l, liig'. i' .is still another modifit'ation showing nitrates made ot a` single pieee of transparent material with a relatively weak or middle portion to provide the desired fiexi` bility7 this view loing an edge view.

in the several views 2 and B represent the lenses and it is the usual noseJbow, the latter to be attached in any desired manner to the Specification of Letters Patent.

middle or flexible portion` whieh in Figs. l., L), Il. i and 5 is a thin plate of` spring;l metal 5 whieh has its ends bent twit'e at'V right anglesA` as shown best in Fie. l, so as to plaee these ends against one side ol the lenses while the intermediate portion is flush with theopposite side oi the lenses. The ends of the flexible sprinpr eonneetion 5 are seein-ed to the lenses in any approved manner, as, tor lnstanee, by serews t3 which. pass through U-shaped fittings 7 and S that engage the lenses and are, at one side, interposed be tween the lenses and the ends of. the eonnertion 5.

fin Fig. (i the eonneetion 5 takes the f'orm of a pair of spring wires t and ttl whieh are secured to the U-shaped fittings T and ti, and in Fig. T the eonneetion is simplyr a thinned `portion of a suitable trausluirent material which permits the lenses and their eonne tion to he in one piet-e. Such materials as eelluloid or miea mayY serve as illustrations of material whii'h may be used l'or the purpose of the nnalifieation shown in Fin. T, which`- perhaps. inthe simplest manner illust 'ates applieantfs invention. ln eaeh oi the forms shown the idea diselosed in liig. 7 is included, namely, a flexible middle portion which serves to hold the lenses S2 and 3 ezitended in'their normal posi ,ions relative to eaeh other, which will flex in a graeeful eurve instead of at n sharp angle as the leaves of hinges, and whieh permit an angie lar adjustment ol eaeh lens relative to the other lens vertit'rally as well as horizontally. l/Vhat is termedthe vertieal adjustment is well illustrated in Fig. 3 where the lenses ineline in opposite direetitms to their verti- 'al positions when in use.

1. I'lhe eombimition with a pair ot' glasses of the elass deseribed, of? a readily flexible eonneetion supporting a nose bow and which yields to bending and twistingr strains and returns the glasses to their normal relative positions.

2. 'lhe etnnbination with a pair of lglasses ot the class deseribed, and with the nosebow for same, of a flexible eonnei'tion joining said ghisses and supportingr said nose' how, said eonneetion supporfiner said glasses in a definite normal position and yet sei-vitrel to permit the relative angular movement ot thel glasses that a hinged connection for same would permit.

3. The combination. with a pair of lenses each other7 said'conneetion having greater of the class described and the nose-bow :for flexibility than said lenses and permitting same, of a flexible connection extending unmovement of eaeh lens relative to the other 15 interruptedly from lens to lens as a supporti lens in planes vertical to each other.` for same and saicb'nose-bow, said flexible ln testimony whereof I have hereunto set connection having 'greater flexibility tlian my hand in the presence of two subscribing said lrlellises` t h 1 lWitnesses: l

4. ie 'com inaion Wit a pair o enses of the class described and the nose-bow for HERMAN J" BRENNECKE same, of a flexible connection on Which said Witnesses: noserbow is mounted and which supports FRANK IHRCKE,
